MAC-HlNE FOR MAKING WIRE ROPE.

SPECIPICATEON forming part of Letters Patent No. 366,422, dated July l2,1887.

Application filed February 10, 1886.

To all whom, it may concern:

Beit known that I, ROBERT STIRLING NEW- ALL,of the borough ofGateshead,in the county of Durham, England, have invented certain newand useful Improvements in Machines for Making Vire Ropes, of which the'following is a specification, reference being had to the drawingsforming part thereof, in which- Figurelisasideview ofthe machine.Fig.2is an end view of the front bearing-wheels and frame. Fig. 3 is aplan of the drawing-gear and the forward end ofthe twisting-machine.Fig. 4. is a plan View of a piece ofthe completed rope. Fig. 5represents one ofthe strands; and Fig. 6 shows a detail sectional viewofthe forward end of one ofthe bobbin-frames and the guide o and nozzlew, the forward end of the main shaft and the layingplate being alsoshown, and a detail View incross-section of the forward end of thebottom frame.

The invent-ion will be first described, and then pointed out in theclaims.

c is the main shaft of the machine, which has a hole through it for thecore of the rope to pass through. It has fixed on it at right angles thedrivin g-wheel ai, Worked by motive power, the back arms, b, andthefront arms, c, each having six or other required number of bearings forsupporting the strand-frames A, which rotate in the bearings iii thearms b and c. Each frame is constructed to hold the number of bobbinsA', each containing a separate wire, A?, necessary to make a strand, A,and one bobbin containing the core At, which may be made of wire or hempor other material.

In the top part of Fig. 1 the strandframe A is in side elevation,showing the three central bobbins, which are shown in plan at the bottomofthe said figure. At the backs ofthe mai ii arms b there are wheels forcausing the strand frames to rotate backwardly in their bearings oncefor each revolution they make round the axis of shaft a. These consistof a bevel-wheel, b', xed ou the end of each bobbinframe, and awheel,b2, of the same size, fixed to the supporting-pillar a', through whichthe main shaft a works. Two pinions, b3, of equal size, are fixed oneach sha-ft 1f, and communicate inotion to the frame-wheels by beingcarried round the fixed wheel, and thus the torsion of Serial No.191,452. (No model.) Patented in England April13,l885, No. 4,559.

the wires and the strands is prevented while they are being laid into arope. The front arms, o, form awheel, C, which rotates on two otherwheels, d and e, supported in a frame,O,

forming the front bearing of the machine, as u shown in Fig. 2. Thesethree wheels are V- grooved on the surface, so as to have more adhesionbetween C and d, and at the same time to prevent the machine being drawntoward the drawing-gear. There is fixed on the outer end of the axle ofthe wheeld, Fig. l, atoothed wheel, f, which works into another wheel,g, which .is supported by a swinging link, g', hanging from the axle d',and working concentrically with the wheelf, so as to be always in gearwith it.

h is one of a set of change-wheels of diferent diameters proportional toa gear-wheel, i, by means of which the draw is regulated. Thechange-wheels h slip on a tube or sleeve, one end of which is fixed inwheel' g, so that wheels g and 7i rotate together on a pin projectingfrom the swing-link g', and as Wheel 7L gears into z' the required speedis given to the wheel i, which is fixed on the shaft i', which carriesat the other end the bevel-wheel j, working into another bevelwheel, k,on the axle of which is fixed the toothed wheel Z, which works into thewheel m, fixed on the side of the drawing-drum m, as shown in thedrawings. There are two bevel-wheels 7c, one on each side of n, so thatby pushing one into gear with a and pushing the other out either rightor left hand ropes are made. These wheels k have setscrews passedthrough their hubs for holding them when adjusted on their shaft.

On the bed-plate which supports the front bearings there are also fixedfour upright pillars, O2, which carry the four drawing-rollers D anddrum m and wheelsnp 1' u o q s t. On the two lower shafts are fixed twotoothed wheels, a p, which gear into wheel m, and on the same lowershafts, and under the wheels o' a, are fixed two other wheels, o q,which gear into wheels o' u, and these into wheels s i, which are fixedou the upper shafts. On the four shafts which carry the wheels 1 s tuthere are grooved drawing-rollers D,which are capable of sliding alongthe shafts on keys letinto IOO the shafts, so as to couple the shafts.and rollers together, and so as to bring the propersized grooves in aline with the axis ofthe main shaft a. These rollers grip the rope, andby the rotation of the machine and the action of the wheels describedthey draw off from the bobbins a certain lengt-h of wire-for i eachrotation of the machine, and so form a rope composed of strands of wiresA3, which strands are not subjected to torsion, as is usual inrope-making; but the rope may be drawn by taking several turns of itround the drum without using the rollers, or it may be drawn by thecombined action of rollers and drum, for they both go at the samesurface-speed.

The wires from the bobbins pass through the front journal of thestrand-frame, where they are symmetrically arranged round a core, andthey also separately pass through the guides v and nozzles '10, whichproject from each frame, and which rotate in the plate a'. Thebobbin-frames are tubular at their forward or inner ends, and the coresfrom the several bobbin-frames pass entirely through these tubular ends,while the several wires enter said tubular portions and pass outwardtherefrom through six apertures, 1.

The guides v are formed of plates secured to or formed on the saidtubular portions and having in the present instance six apertures,through which the wires pass from the apertures 1. The nozzles w arealso provided with six apertures to receive lthe wires from the guides oand are screw-threaded to engage screw-threads on the extreme ends ofthe tubular portions of the said bobbin-frames, as

clearly shown in Fig. 6, and these nozzles rest in bearings in the platex, so that they form the journals of the inner ends of the tubularportions of the bobbin-frames. The wires from each strand-frame beingthus kept separate and without being subjected to torsion, are laid inseparate strands or sets round a core into a ropewithout being laid ortwisted together in the usual way of making wire rope.

I have illustrated the description of my invention by drawings of amachine in which the main shaft is horizontal, which I prefer to havingthe main shaft perpendicular; but my improvement is easily applied to aperpendicular machine so long as the strand-frames make one rotation ontheir axes while the inachine rotates once.

The drawings show a machine for making ropes of six strands, each strandhaving six wires and a core; but machines may be made having any othernumber of wires, cores, and strands. d 4
